Pick a company that pays dividends, then calculate the expected growth rate of your company using the CAPM.
Once this task is complete, calculate the expected growth rate using the Constant Growth (or Gordon Growth) Model.
You may need additional information to complete this exercise. You can find a stock's beta and growth rate at https://quote.yahoo.com/. Once there, enter the ticker for the company in question. Then, click on "Key Statistics" about halfway down the left hand side of the page. You can find the beta here.
